  • Castings in the World – Casting The Future

    2021-6-27 · Made by pouring molten metal into a mould, castings can be used to make parts of complex shapes that would be difficult or uneconomic to make by other methods (such as forging, assembling components or cutting from solid material). The castings industry is growing and more than 100 million tonnes of casting were produced globally last year, more than ever before!
